golang: how to replace "\n" with "<br>"
问题
我试过使用strings.Replace(s,"\n","<br>",-1);来做这个。但是结果是不同的，它在网页浏览器中显示为<br>，但实际上不是"<br>"。有人可以告诉我如何做到这一点吗？
我的主要目标是将<textarea>中的换行符更改为html中的<br>标签。
任何线索都将受到欢迎，提前感谢。
PS：
问：你是想从数据库中获取它吗？
答：是的，我从GAE的数据库中获取字符串，然后用<br>替换\n。从数据库中获取的字符串有什么不同吗？
英文:
I tried to do it using strings.Replace(s,"\n","<br>",-1);
But the result is something different which could be displayed as <br> in a web browser but is in fact not "<br>". Can anyone tell me how to do this?
My primary goal is to change the end of line character from a <textarea> into a <br> tag in html.
Any clue would be welcome, thanks in advance.
PS:
Q: Are you trying to get it from database?
A: Yeah, I get the string from GAE's database, and then replace \n with <br>. Is there anything different with string from database?

你的代码中其他地方可能存在问题 - 可能是在将输出放入模板时进行了转义？你发布的代码行将换行符替换为br，并且是正确的 - 可以参考这个简单的测试：
package main
import("strings")
func main() {
s := "我是一个包含换行符的字符串\n"
s = strings.Replace(s,"\n","<br>",-1)
println(s)
}
你需要发布更多的代码，以便其他人可以找到你出错的地方，例如发布创建/操作字符串的函数以及输出到HTML的模板部分。
在Go playground上查看 - http://play.golang.org/p/KMzxku4UtL
英文:
There is a problem elsewhere in your code - perhaps the output is being escaped when put into a template? The line you have posted will replace newlines with br and is correct - see this simple test:
package main
import("strings")
func main() {
s := "I am a string\nContaining new lines"
s = strings.Replace(s,"\n","<br>",-1)
println(s)
}
You'd need to post more code than this for people to find where you are going wrong, for example post the function which creates/manipulates the string, and the bit of template where it is output to html.

问题已解决。
问题出在模板文件中。我使用了 |html 来转义内容。当我在代码中移除了 "|html"，一切都正常了。
感谢大家的帮助。

https://stackoverflow.com/users/296559/robotamer got it right. Problem solved.
The problem is in the template file. I used |html to escape the contents. When I removed "|html" in the code, everything is fine.
Thank you all for your help.
